director, official, govt office, rule, administer
司 centers on the idea of being in charge: a director, official, or government office that rules and administers.
司 is thought to combine a person-like element with 口 (mouth), suggesting someone giving orders or administering. The exact historical development is uncertain.
The top looks like a person reaching out, and the bottom 口 is a mouth giving commands. Picture a director issuing orders from a government office.
For シ, imagine a director named She who rules the office: She -> シ, and she administers everything.
